Aquatic feed should add vitamin C

Vitamin C, also known as ascorbic acid, has an important physiological role in fish and shrimp. Insufficient vitamin C intake of fish and shrimp, easily cause vitamin C deficiency, impede the normal growth and development of fish and shrimp, and even cause death, it is necessary to add vitamin C in aquatic feed.

It is worth noting that the theoretical demand for vitamin C in fish and shrimp is very different from the actual amount added. Because vitamin C has a strong reduction, it is very unstable, easy to be air oxidized in alkaline or acidic solution, UV, heating and metal ions and other physical and chemical factors can also make vitamin C destroyed. Therefore, in the process of making feed, the actual amount of vitamin C added should be greater than the theoretical demand. At present, the actual amount of vitamin C added in the feed is mainly based on two points: first, the nutritional requirements of the relevant species, and second, the stability of the varieties used. The recommended amount of vitamin C in the feed is generally 4 to 5 times the demand.
